超声波防治海生物的技术分析与应用

文章阐述了海生物附着生长的机理以及传统海生物防治的方法。针对传统海生物防治方法存在的不足之处,提出超声波防治海生物技术,分析了超声波振动性质和空化效应防治海生物的原理及现场应用情况,并确定出有效防治海生物的超声波频率为22kHz,强度为0.3～0.5 W/cm2;通过现场实际应用,充分证明了超声波能够有效抑制海生物的附着和生长,保护海水管线及相关设备,体现了超声波技术在海生物防治方面具有环保、节能、易于维护等优点。

Analyses and Application of Marine Organism Prevention and Control Technology by Ultrasonic Waves

The paper elaborates on the mechanism of marine organism attached growth and the conventional methods of marine organism prevention and control.Because of the disadvantages of the conventional methods,this article introduces marine organism prevention and control technology by ultrasonic waves and analyzes the principles and applications of ultrasonic vibration and cavitation properties to prevent and control marine organisms.Besides it identifies the effective prevention and control ultrasonic frequency and intensity as 22 kHz and 0.3-0.5 W/cm 2 respectively.Through the practical applications,it has proved that the ultrasonic waves can effectively prevent marine organism attachment and growth and protect the seawater pipelines and the equipments which reflect the fact that ultrasonic wave technology is environmentally friendly,energy saving and easy to maintain in marine organism prevention and control.
